Lege Artis Medicinae - 2004;14(10)

[The author deals with the current situation and new trends of vaccinology by focusing on the interests of practitioners. The main topics are the changes of antigens (such as pertussis, measles, or poliomyelitis) to provide better efficacy and milder reactogenity or less adverse events. Purifying the vaccines, like thiomersal and human proteins free vaccines is another proven method to achieve better safety. New antigens e.g. Rota, Lyme, meningococcus B are in the pipeline of vaccinology. The aim of producing a combined vaccine is to achieve immunity against more diseases with less inconvenience for the patient, while achieving higher vaccine coverage (DPT-Hib-HBV-IPV). The epidemiological and clinical experiences will influence the current vaccine schedule such as revaccinations of MMR, and remove the need for revaccinations of BCG and hepaB. The special target groups of immunizations are the elderly and patients with chronic disease. Groups of specialists are working on the vaccine recommendation guidelines for certain risk groups. At the same time, with the successful eradication of polio in Europe the practitioners now have to face the antivaccination movement, as well. The main tools to convince people about the benefit of vaccinations are health education and information.]

[SUCCESSFUL TREATMENT OF WHIPPLE'S DISEASE IN A PATIENT WITH LYMPH NODE ENLARGEMENT]

SOMOGYI Ágota, SZABÓ Tamás, KISHÁZI Péter, KISS Erika, ARATÓ Gabriella, PÁL Katalin, MADÁCSY László

[INTRODUCTION - Intestinal lipodystrophy, Whipple’s disease is an uncommon, chronic, systemic bacterial infection. It occurs predominantly in Caucasian males older than 40 years. The gastrointestinal tract is the most frequently involved organ, with clinical manifestations such as abdominal pain, malabsorption syndrome with diarrhea and weigth loss. Patient may present with low grade fever or fever of unknown origin, arthritis, lymphadenopathy, skin hyperpigmentation, endocarditis, pleuritis and peripheral and central neurological manifestations. Due to the wide variability of symptoms, the clinical diagnosis is very difficult and it is often made only years or even decades after the initial presentation. CASE REPORT - A 51-year-old Caucasian race man was admitted to the hospital with weigth loss and signs of subileus, referred for suspected lymphoma. After the exploratory laparotomy and lymphadenectomy the histological and the electron microscopical diagnosis was Whipple’s disease which was confirmed with histology from deep duodenal biopsy. Trimethoprim and sulfamethoxazole therapy for 6 months resulted in complete clinical and molecular biological healing. CONCLUSION - Clinical signs of Whipple’s dease are non-specific and may mimic Crohn’s disease, coeliac disease, amyloidosis, macroglobulinaemia, histoplasmosis, infection with non-tuberculotic mycobacterium in AIDS patients and lymphomas. Therefore, differential diagnosis is of critical importance. The natural evolution of the disease without treatment is always fatal. Trimethoprim and sulfamethoxazole for at least 1 year is usually considered adequate to eradicate the infection.]

[LONG-TERM RESULTS OF ENDOSCOPIC SPHINCTEROTOMY - EFFECTS OF THE TRANSECTION OF BILE PAPILLA]

DÖBRÖNTE Zoltán

[The abolishment of the choledochoduodenal pressure gradient due to endoscopic sphincterotomy results in the enhancement of the enterohepatic circulation of the bile salts, in the reduction of the cholesterol saturation index and in the modification of the gallbladder function: the reduced gallbladder storage time and the increased ejection fraction facilitates gallbladder emptying. On the contrary, bacterial colonisation of the bile ducts due to duodenobiliary reflux plays a causative role in the increased risk of pigment stone formation. However, when the biliary tree is well-drained, no clinically relevant chronic inflammation develops, furthermore there is no evidence for an increased cancer risk caused by the duodenobiliary reflux. Long-term complications may occur in about 12%, as the recurrence of common bile duct stones, post-EST papillary stenosis, and biliary symptoms caused by retained gallbladder stones. Risk factors for recurrence of bile duct stones are juxtapapillary duodenum diverticulae and persistently dilated bile ducts being the main reason for papillary restenosis and sphincterotomies are mainly performed because of papillary stenosis. In cases of retained gallbladder with stones patency of the cystic duct and contractility of the gallbladder are important predictive factors of late gallbladder complications as it was confirmed by our investigations. Accordingly, small gallbladder stones may pass spontaneously after EST. The indication of a cholecystectomy following EST should be considered individually, particularly in elderly patients. As 30-year-experience confirms, EST is a safe and effective treatment of choledocholithiasis and papillary stenosis even in the long term, and also in young patients. Regular follow-up of patients with high risk for recurrent biliary symptoms is recommended to detect late complications and treat them endoscopically in time.]

[THE SIGNIFICANCE OF THE CARE OF CHILDREN WITH CLEFT LIP AND PALATE IN THE GENERAL PRACTICE]

HIRSCHBERG Jenő

[The cleft lip and palate (i.e. facial cleft) is a frequent and distorting abnormality. The basics of the successful management are the early introduction of therapy and a well-trained team with all relevant specialists included (surgeon, otolaryngologist, orthodontist, speech therapist) as well as good collaboration with the parents and general practitioners being also an important factor. The author with his co-workers has performed more than 6000 surgeries in about 3500 children with facial cleft in the last 45 years and has treated 60-70 patients annuallly with velopharyngeal insufficiency without cleft. According to his experience and international data he summarizes the etiology, pathomechanism of facial clefts and discusses its symptoms, functional consequences and the surgical and conservative solutions are suggested. The recent Hungarian prevalence is 1:500. Specific prevention does not exist, the 5-6% recurrent cleft risk may be decreased to half by administration of folic acid. The generally accepted timing of the lip plasty is the 3-month age. The palatoplasty may be performed in one or two stages, but closure of the velum should be made before the development of speech by all means. The logopedic treatment (speech therapy) should be started, if the speech disorder is already obvious and the child is able to cooperate with the speech therapist. If conservative therapy is unsuccessful, (velo)pharyngoplasty is proposed at the age of 5. The orthodontic treatment should begin in mixed dentition, major nose correction and oral surgery are allowed only after puberty. Just because of a cleft the infant does not aspirate, the brestfeeding is beneficial and could be performed in most cases. Regular hearing control is recommended because of frequent ear and hearing problems. It is suggested to provide the parents with written instruction about outcome, prognosis and timetable of management, which could be helpful also for the general practitioners.]

Electrophysiological investigation for autonomic dysfunction in patients with myasthenia gravis: A prospective study

NALBANTOGLU Mecbure, AKALIN Ali Mehmet, GUNDUZ Aysegul, KIZILTAN Meral

Myasthenia gravis (MG) is an autoimmune disorder of neuromuscular transmission. Autonomic dysfunction is not a commonly known association with MG. We conducted this study to evaluate autonomic functions in MG & subgroups and to investigate the effects of acetylcholinesterase inhibitors. This study comprised 30 autoimmune MG patients and 30 healthy volunteers. Autonomic tests including sympathetic skin response (SSR) and R-R interval variation analysis (RRIV) was carried out. The tests were performed two times for patients who were under acetylcholinesterase inhibitors during the current assessment. The RRIV rise during hyperventilation was better (p=0.006) and Valsalva ratio (p=0.039) was lower in control group. The SSR amplitudes were lower thereafter drug intake (p=0.030). As much as time went by after drug administration prolonged SSR latencies were obtained (p=0.043).Valsalva ratio was lower in the AchR antibody negative group (p=0.033). The findings showed that both ocular/generalized MG patients have a subclinical parasympathetic abnormality prominent in the AchR antibody negative group and pyridostigmine has a peripheral sympathetic cholinergic noncumulative effect.

[What has Go to do with making clinical decisions? One of the greatest intellectual challenges of bedside medicine is making decisions under uncertainty. Besides the psychological traps of traditionally intuitive and heuristic medical decision making, lack of information, scarce resources and characteristics of doctor-patient relationship contribute equally to this uncertainty. Formal, mathematical model based analysis of decisions used widely in developing clinical guidelines and in health technology assessment provides a good tool in theoretical terms to avoid pitfalls of intuitive decision making. Nevertheless it can be hardly used in individual situations and most physicians dislike it as well. This method, however, has its own limitations, especially while tailoring individual decisions, under inclusion of potential lack of input data used for calculations, or its large imprecision, and the low capability of the current mathematical models to represent the full complexity and variability of processes in complex systems. Nevertheless, clinical decision support systems can be helpful in the individual decision making of physicians if they are well integrated in the health information systems, and do not break down the physicians’ autonomy of making decisions. Classical decision support systems are knowledge based and rely on system of rules and problem specific algorithms. They are utilized widely from health administration to image processing. The current information revolution created the so-called artificial intelligence by machine learning methods, i.e. machines can learn indeed. This new generation of artificial intelligence is not based on particular system of rules but on neuronal networks teaching themselves by huge databases and general learning algorithms. This type of artificial intelligence outperforms humans already in certain fields like chess, Go, or aerial combat. Its development is full of challenges and threats, while it presents a technological breakthrough, which cannot be stopped and will transform our world. Its development and application has already started also in the healthcare. Health professionals must participate in this development to steer it into the right direction. Lee Sedol, 18-times Go world champion retired three years after his historical defeat from AlphaGo artificial intelligence, be­cause “Even if I become the No. 1, there is an entity that cannot be defeated”. It is our great luck that we do not need to compete or defeat it, we must ensure instead that it would be safe and trustworthy, and in collaboration with humans this entity would make healthcare more effective and efficient. ]

[Evaluation of clinical practices among academic nursing students]

NAGY-GÁL Anetta

[Purpose: Establishing a balance between theoretical and practical training is essential in the training of college nursing students. The aim was to assess the students’ experiences of clinical practice and the problems they indicate in the component, which plays an important role in preparing the training for professional competencies. The study sample consisted of 3rd and 4th grade students (N=96) participating in nursing training at the Faculty of Health Sciences of Semmelweis University. The method of data collection was based on the completion of a quantitative online questionnaire, which also included qualitative elements in the form of three open-ended questions. Among the statements measured on the Likert scale, the balance of theory-practice, the role of participants in education, and the time spent on practical tasks received lower average ranks from both grades. Logistic regression is suitable for estimating the probability of a positive/negative impression of a practice as a combined effect of several explanatory variables. Compared to the results of a previous (2009) study, the problems with field clinical training remain unresolved.]

The effect of sniffing Turkish coffee on olfactory disorders in COVID-19 patients: An experimental clinical study

BULBULOGLU Semra, ALTUN Yasar

The current study aimed to examine the effect of sniffing Turkish coffee on the sense of smell in COVID-19 patients. This study utilized the experiment-control method. Data were collected using a patient and disease information form and the Connecticut Chemosensory Clinical Research Center (CCCRC) Test. An experimental group of patients sniffed Turkish coffee, and the coffee’s effect on the patients’ sense of smell was examined. All data were analyzed using SPSS version 25 (IBM). Of the patients in the experimental group, 25% had moderate hyposmia, 58.3% had severe hyposmia, and 16.7% had anosmia prior to sniffing Turkish coffee. After sniffing the Turkish coffee, 13.3% of these patients regained their ability to smell normally, while 18.3% had mild hyposmia, 45% had moderate hyposmia, 6.7% had severe hyposmia, and 16.7% had anosmia. There was no difference in the control group between first and second measurement. COVID-19 patients who sniffed Turkish coffee intermittently regained some of their sense of smell for one hour. Turkish coffee is cheap, fragrant, widely available, and easy to access. Therefore, results of this study suggest that it may be recommended for treating olfactory disorder in COVID-19 patients.

[Neuropsychological rehabilitation following acquired brain injury]

TAMÁS Viktória, KOVÁCS Noémi, TASNÁDI Emese

[Neuropsychological rehabilitation or rehabilitation neuropsychology is a field within applied neuropsychology. It originally diverges from applied clinical and functional neuropsychology, although it could not be entirely differed from them. The unique nature of this area over the complexity is given by its process-controlled and system-approach aspects. In Hungary the number of neurorehabilitation centres and departments requiring neurocognitive rehabilitation has been continually increasing. Nevertheless, the number is still low; accordingly in our country this field is relatively young and isn’t well known. Authors of this review would like to draw attention to the importance of rehabilitation of patients with acquired brain injury and improvement of their quality of life with the theoretical and practical knowledge, as well as the necessity of future alterations and challenges emphasizing the need of a significant change of this narrow domain. ]
